Original application April 21, 1951, Serial No. 222,240,

now Patent No.- 2,709,427, dated May 31, 1955. Dividletioand thisapplication August 20, 1954, Serial No. 45 4 3 Claims. (Cl. 131-408)This application relates to tiltable pan humidifiers, an example ofwhich is shown in the patent to Perlman 2,588,567 of March 11, 1952.

This application is a division of application Serial No. 222,240, filedApril 21, 1951, now Patent No. 2,709,- 427 of May 31, 1955, entitledHumidifier, in turn a continuation in part of application Serial No.150,880, filed March 21, 1950, and now Patent No. 2,588,567 of March 11,1952.

One object of the invention is to provide a tiltable pan humidifierwhich is easily and readily installed in off vertical as well asvertical furnace walls and ducts to level the pan in any slope of wall.

Other objects of the invention will become apparent by reference to thefollowing detailed description taken in connection with the accompanyingdrawing in which:

Fig. 1 is a longitudinal vertical sectional view of a humidifierembodying the invention mounted on and through a vertical wall.

Fig. 2 is a fragmentary horizontal view taken substantially on the line2-2 of Fig. 1.

Fig. 3 is a section view as if on line 33 of Fig. 1.

Fig. 4 is an elevation view but showing the humidifier mounted in asloping or off vertical wall.

Referring to the drawing, it will be observed that it shows a support inthe form of a hollow box having open forward and rear ends, with theopen forward end being closed by a removable snap-on cover 11..

The vertical sides of the box are formed with lugs 12 whose upper edgesprovide pivotal bearings for V- shaped formations 14 of the horizontalflange 15 of a water pan or reservoir 16 whereby the latter is removablyand pivotally mounted in the support 10 on a horizontal transverse axisbetween the longitudinally spaced ends of the pan.

At 17, is shown a nozzle of a water supply line connected to the topwall of the support forward of the pivotal axis 1214.

The pan 16 tilts and balances itself on its pivot axis 12--14 accordingto the quantity of water in the rear end of such pan and when the pan isfull, a stopper 18 in the forward end of the pen engages the lower endof the nozzle 17 of the inlet line to close it. Conversely when the panis not adequately filled, water pressure in the line 17 will tilt thepan counterclockwise to open the nozzle and admit water. This ischaracteristic of the action of a tilting pan humidifier.

It will be observed that the pan is removably mounted within the boxsupport on its pivot axis 12-14, with access into the box support forsuch purpose being provided by the removal of the snap-on cover 11closing the forward open end of the box.

An adjustable means is provided which is adapted to be secured by screws19 against a wall 20 of a furnace or duct and for thus mounting thesupport in a hole of that wall. Such adjustable means, hereafter knownas a mounting means, comprises a U-shaped mounting plate 21 extendingalong the bottom and sides of the box sup- Patented June 12, 1956 port10 and having lugs 22 connected to the sides of the box by screws 23 inslots 24 of lugs 22 with the free ends of the U-shaped plate extendingabove the box support.

The top edges of the sides of the support are formed with a plurality oflongitudinally spaced detents 26 for cooperation with an anchor plate 27which is connected to the upper ends of the sides of the mounting plate21 by screws 23 and thus clamps the support to the mounting plate in anyadjusted position whereby the mounting plate may be tilted forwardly andrearwardly with respect to the support for level mounting of the supportin the mounting plate regardless of the slope of the wall to which themounting plate is secured.

The interior of the box is visible when cap 11 is removed to expose toview a plumb bob 36 suspended on a pivot point 37 on a side of the boxand cooperating with a target mark 38 in the box for indicating that thesupport 10 is truly level regardless of the slope of the wall 20 and ofthe adjusted position of the mounting plate 21 with respect to thesupport 10.

Now having described the construction herein disclosed, reference shouldbe had to the claims which follow.

I claim:

1. In a humidifier, a support having an open rear end, means formounting it horizontally part way through a wall comprising a U-shapedmounting plate extending along the bottom and sides of said support andpivotally mounting it therein with the free ends thereof extending abovesaid support, a portion of said support having a plurality oflongitudinally spaced detents formed therein along the top thereof, andan anchor plate disposable in selected detents at the top of saidsupport including means for securing said anchor plate to said U-shapedmounting plate, a longitudinally extending open top reservoir,horizontally disposed in said support and having a forward end and arearward end and pivotally supported and balanced between its ends insaid support on a horizontal axis transverse to the longitudinal axispassing through its ends to pivot downwardly at its forward end whenrelatively empty and upwardly at its said forward end when filled, anozzle disposed through the top of the forward end of said support overthe forward end of said reservoir through which water under pressure iscontinuously available from a water supply to fill said reservoir,stopper means in said reservoir forward end for contacting said nozzleand shutting off water supplied to the reservoir therethrough responsiveto the upward tilting of the forward end of said reservoir when saidreservoir is filled.

2. In a humidifier of the tiltable pan type, a hollow box support,having open forward and rear ends, a water pan pivotally mounted thereinon a horizontal transverse axis between its ends, a water supply lineconnected to said support forward of said axis and an adjustable supportmounting means adapted to be secured against a wall and to said supportand thus mounting said support in a manner to tilt forwardly andrearwardly with respect to said support for level mounting of saidsupport in said mounting means regardless of the slope of said wall andof said mounting means, and means for detachably securing said mountingmeans to said wall and also to said support in adjusted position, saidmounting means comprising a U-shaped plate surrounding said box and aseparate bridging plate positioned to connect the ends of the U of themounting plate, and detents formed on the box support for selectivelyreceiving the bridging plate and clamping the box in adjusted positiontherein.

3. A construction of the character described in claim 2 including avisible plumb bob and target permanently mounted on the support forvisibility indicating whether 3 4 or not the support is truly level orhorizontal when References Cited in the file of this patent mounted inthe mounting plate, and thus facilitating level UNITED STATES PATENTS t.mountmg of the supp 2,557,042 Woolley June 12, 1951 2,565,210 DovolisAug. 21, 1951 2,588,567 Perlman Mar. 11, 1952
